Seamless paper reel

ABSTRACT

A paper reel includes a lining, and an enclosure mounted on a periphery of the lining. Thus, the plastic enclosure encompasses a whole length of the paper lining to reinforce the strength of the paper reel, so that when an element, such as a tape, cloth, weaving strap, metallic foil, car insulating paper or the like, is closely wound around the paper reel, the paper reel will not be deformed or distorted due to compression, thereby enhancing the quality and stability of the paper reel.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a paper reel, and more particularly toa seamless paper reel for winding a tape, cloth, weaving strap, metallicfoil, car insulating paper or the like.

2. Description of the Related Art

A conventional paper reel is used for winding a tape, cloth, weavingstrap, metallic foil, car insulating paper or the like, and comprises alining including a plurality of paper strips overlapping each other inan oblique manner to form a tubular body, and a paper strap wrappedaround a periphery of the tubular body formed by the paper strips.However, the conventional paper reel has a weaker strength, so that itis easily deformed or distorted due to compression, thereby decreasingthe quality of the conventional paper reel.

SUMMARY OF THE INVENTION

In accordance with the present invention, there is provided a paperreel, comprising:

a lining; and

an enclosure mounted on a periphery of the lining.

The primary objective of the present invention is to provide a seamlesspaper reel.

Another objective of the present invention is to provide a paper reel,wherein the plastic enclosure encompasses a whole length of the paperlining to reinforce the strength of the paper reel, so that when anelement, such as a tape, cloth, weaving strap, metallic foil, carinsulating paper or the like, is closely wound around the paper reel,the paper reel will not be deformed or distorted due to compression,thereby enhancing the quality and stability of the paper reel.

A further objective of the present invention is to provide a paper reel,wherein the lining is formed by a winding process, and the plasticenclosure is made by a plastic injection molding process, so that thepaper reel is made easily, exactly and rapidly, thereby enhancing theworking efficiency and decreasing costs of fabrication.

Further benefits and advantages of the present invention will becomeapparent after a careful reading of the detailed description withappropriate reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION

Referring to the drawings and initially to FIGS. 1-3, a paper reel inaccordance with the preferred embodiment of the present inventioncomprises a lining 10, and an enclosure 20 mounted on a periphery of thelining 10.

The lining 10 includes a plurality of paper strips 11 overlapping eachother in an oblique manner, and a plurality of grooves 12 locatedbetween the paper strips 11 in an oblique manner. Preferably, thegrooves 12 of the paper strips 11 are arranged in a helical manner. Thepaper strips 11 are wound around a helical winding track in an obliquemanner so as to form a tubular body. The paper strips 11 are juxtaposedto each other in an oblique manner.

Referring to FIGS. 1-4, the lining 10 further includes a paper strap 13mounted between the paper strips 11 and the enclosure 20. The grooves 12of the paper strips 11 are covered by the paper strap 13 completely. Thepaper strap 13 is substantially tubular and has a length equal to thatof the tubular body formed by the paper strips 11. The paper strap 13 isradially wrapped around a periphery of the tubular body formed by thepaper strips 11. The paper strap 13 is harder than each of the paperstrips 11.

The enclosure 20 is made of plastic material. The enclosure 20 issubstantially tubular and is wrapped around a periphery of the paperstrap 13.

In assembly, an adhesive is bonded on a side of each of the paper strips11. Then, each of the paper strips 11 is wound around a helical windingtrack of a winding machine in an oblique manner with a determined pitch,so that each of the paper strips 11 is bonded layer by layer so as toform a tubular body. In addition, the paper strips 11 are juxtaposed toeach other in an oblique manner to form the grooves 12. Then, anadhesive is bonded on a side of the paper strap 13 and the paper strap13 is radially wrapped around the periphery of the tubular body formedby the paper strips 11 so as to form the lining 10. In such a manner,the grooves 12 of the paper strips 11 are covered by the paper strap 13completely. Finally, the lining 10 is mounted in a tubular die and aplastic material is injected into the die to form the enclosure 20 whichis wrapped around the periphery of the lining 10. Thus, the lining 10and the enclosure 20 form a seamless paper reel as shown in FIG. 1.

Accordingly, the plastic enclosure 20 encompasses a whole length of thepaper lining 10 to reinforce the strength of the paper reel, so thatwhen an element, such as a tape, cloth, weaving strap, metallic foil,car insulating paper or the like, is closely wound around the paperreel, the paper reel will not be deformed or distorted due tocompression, thereby enhancing the quality and stability of the paperreel. In addition, the lining 10 is formed by a winding process, and theplastic enclosure 20 is made by a plastic injection molding process, sothat the paper reel is made easily, exactly and rapidly, therebyenhancing the working efficiency and decreasing costs of fabrication.

Although the invention has been explained in relation to its preferredembodiment(s) as mentioned above, it is to be understood that many otherpossible modifications and variations can be made without departing fromthe scope of the present invention.
